for what part roller bearingd for the small end bearings ans swing arm, Ball bearings for the mains and gear box and wheel bearings, Caps for the cam shaft and the big ends Thrust for the clutch Could you be a little more specific? I was being generic :-)
Phillip missed it on several points. The crankshaft main bearings and con rod big ends are replaceable plain bearings, small end rod are non-replacable plain with full floating wrist pin, camshaft plain, tranny shafts are caged ball bearings, steering head are loose balls (really cheap crap), swing arm pivot are plastic bushings (really, really cheap crap) and the wheel bearings are caged balls. You should be able to replace the steering head and swing arm with tapered roller bearings, which will really improve handling.
